ninenn WINDOW.

Application filed April 25, 1925. Serial No. 25,933.

To all whom it may concern:

Be it known that I, GEORGE DREW, subject of the King of Great Britain, residing at lilontreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Hinged Windows; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention pertains to novel improvements in windows of the type having slidable sashes which are also capable of a swinging movement on hinges.

The principal object of the invention is the provision of a window of this character, the cleaning of which is facilitated by the fact that the sashes are capable of inward swinging movement. lvloreover, the device is so constructed that the sashes may be raised or lowered while swung inwardly, and a still further object of the invention is to enable storm sashes and fly screens to be safely fixed while the person doing this work is standing on the floor that is located nearest the window.

The invention embodies a slotted and grooved pulley style, one side of which is engaged by cord holders and the other side by hinges carrying the window sashes, the hinges being attached to the cord holders by means of members passing through the style. Due to this construction, broken sash cords and window panes may be more readily replaced or repaired than in devices of present construction. Economy in cost of construction is made possible by the fact that only one pair of sash cords, sash weights and sash pulleys are required, as compared with two pairs of each of these members necessary in ordinary house windows. Still another advantage of the invention is that no rattling or tilting of the window sashes occurs, there being provided special guide pins for preventing these defects. The invention is of such a nature that it may be applied to existing boxed window frames by merely cutting a slot in the pulley style and in the opposite parting bead, and then applying the cord holders and hinges embodied in the subject matter of the invention.

The invention is fully disclosed in the following description and in the accompanying drawings in which:

Figure 1 is an elevation of the device, partly in section;

Figure 2 is a side elevation showing the pulley style, weights and cords;

Figure 3 is a horizontal section through the pulley style and hinged ends of the sashes;

Figure 4 is a similar section showing the sashes swung inwardly;

Figure is a fragmentary elevation, partly in section, showing a hinge attached to one of the cord holders; and,

Figure 6 is an outside elevation of one of the cord holders.

Reference will now be made to these views by the use of like characters which are employed to designate corresponding parts throughout.

The numeral 1 indicates in general a window frame one side of which comprises the pulley style 2 constructed in the particular manner required by the invention. In its outer face the style is formed with a pair of grooves 3, while slots 4 extend from the bottom of the grooves through the style to the inner face. The inner face is formed with a pair of grooves 5 parallel to one another and opposed to the grooves 4 as illustrated in Figures 3 and 4. Intermediate the grooves 5, a parting head 6 is inserted in the style and runs longitudinally thereof. Each outer groove 4 receives a pair of cord holders, each of which consists of a plate 7 and a ring 8 extending therefrom. The plate is formed with a threaded aperture 9 in its face and an annular groove 10 surrounding the same. The plates lie entirely within the grooves 4 as clearly shown in Figures 3, 4 and The inner grooves 5 partially receive angular hinge leaves 11, the remaining sides extending into the space defined by the window frame as illustrated in Figures 3 and 4. These sides 11 carry screw pins 12 and guide pins 13 which are received in the aperture 9 and groove 10 respectively. In this manner the angular hinge leaves are fixed to the plates, while the pins 13 prevent the leaves from tilting with reference to the plates. It is to be noted particularly that the cord holders are disposed on one side of the pulley style while the angular hinge leaves 11 are located at the opposite side. The remaining sides 11 of the angular hinge leaves are formed with hinge knuckles (it a.

14 adapted for cooperation with similar knuckles 14 on complementary hinge leaves 15. The latter are provided with apertures 16, and window sashes 17 are secured to the members 15 by screws 18 or the like passed through the apertures 16.

Cables 19 are passed through the rings 8 of each pair of cord holders and are trained over pulleys 20 secured .to the top 21 of the window frame. One end of each cable is knotted at 22 beneath the lower ring through which it is passed, and the remaining end carries a weight 23.

The frame side 24L opposite the style embodies a removable strip 25 intermediate its ends. The sashes are adjusted verticall -s in the usual manner, being guided by m:- reception of the cord holders and hinges in the slots of the pulley style. They may also be swung inwardly on their hinges, but prior to this the strip 25 must be removed. One or both sashes are then moved so that the inner end thereof lies between the ends of the slot formed by the removal of the strip The free ends of the sashes are now unobstructed, and the sashes can easily be swung on their hinges. The parting bead (not shown) at this side of the frame should be slotted similarly to the member 2a, to permit swinging of the outer sash 17.

lVhile a specific embodiment of the invention has been illustrated and described, it is to be understood that various alterations in the details of construction may be made without departing from the spirit of the invention as indicated by the appended claims.

Having thus fully described the invention, what I claim as new and desire to protect by Letters Patent is:

1. A Window comprising a frame having a slotted pulley style, cord holders slidably mounted at the outer side of said style, hinges slidably mounted at the inner side of the style, attaching members extending from the hinges through the slots of the style and to the cord holders, sashes secured to said hinges, said cord holders each having a groove in its taco, and pins extending from said hinges and received in said grooves.

2. A window comprising a frame hzwing a slotted pulley style, cord holders slidably mounted at the outer side of said style, hinges slidably mounted at the inner side of the style, attaching members extending from the hinges through the slots of the style and to the cord holders, sashes secured to said hinges, said cord holders each having a groove in its face, pins extending from said hinges and received in said grooves, rings carried by said cord holders, pulleys supported by the frame, cords passed through said rings and over said pulleys, and a weight carried by each of said cords.

1 In witness whereof I have hereunto set my land.

GEORGE DREV.
